John Froines

John Radford Froines (; June 13, 1939 – July 13, 2022) was an American chemist and anti-war activist, noted as a member of the Chicago Seven, a group charged with involvement with the riots at the 1968 Democratic National Convention in Chicago. Froines, who held a Ph.D. in chemistry from Yale, was charged with interstate travel for purposes of inciting a riot and with making incendiary devices, but was acquitted. He later served as the Director of Toxic Substances at the federal Occupational Safety and Health Administration and then director of UCLA’s Occupational Health Center. He also served as chair of the California Scientific Review Panel on Toxic Air Contaminants for nearly 30 years before resigning in 2013 amid controversy and claims of conflict of interest.
